Fr. Joseph Krupp provides a really interesting discussion on courting (dating?), engagement and marriage.
It starts at about 24:30. The material before that is on a completely different topic.
The comments by Fr. Krupp before that are interesting, albeit, as noted, on a completely different topic. Those aren't the reason that I linked this in here, but I am fairly amazed that he hasn't gotten himself in trouble for saying such things as he says in the first half of this video podcast.
